Just in case you can't find them, here are the standard settings;
Front
Caster 3deg10min to 4deg40min
Camber -1deg35min to -0deg5min
Toe 0deg0min to 0deg5min
Rear
Camber -1deg45min to -0deg45min
Toe 0deg0min to 0deg10min
(1st figure is minimum, 2nd figure is maximum)
As for optimal settings, everyone's opinion will be different.....
You'll need to see what works for you.
BTW - Your tyre size is enormous since the stock tyre is 245/40-18
